  1. Smart Power Strips in Commercial Office Applications RTF August 30, 2011

  2. Goal Today • To update UES estimates and move provisionally deemed smart strip measures to active status for commercial office applications • Using updated savings from BPA engineering research

  3. Background • RTF Provisionally deemed smart power strips in a commercial office in March 2010 • 100 kWh • $20/unit • 4 year Measure Life • RTF approved Research Plan • 50 unit sample • 2 week pre/post metering • Collect information on equipment plugged in and settings

  4. Smart Power Strips • Resemble traditional power strips, but have outlets with different functionalities. • Control outlet and controlled outlets • Some also have outlets that will always remain on • Load Sensor • Occupancy Sensor

  5. Smart Power Strips • Load Sensor • When a control device is turned off or enters sleep mode, the Smart Power Strip cuts power to the controlled peripherals: items such as printers, heaters, speakers. • Occupancy Sensor • The occupancy sensor cuts power to the controlled peripherals: items such as printers, heaters, speakers.

  6. Types of Smart Power Strips

  7. BPA Metering Study • Details about the research activities • A total of 48 smart strips installed • Installed at Ross Complex, Vancouver, WA • Approximately 3 weeks baseline and post metering time during April/May 2011 • Kill-A-Watt Meters used for data collection • ‘Current Sensing’ Smart Power Strip was installed • Load sensor device

  8. Example of Results

  9. Results Summary • Savings details • Sample size = 45 cubicles/offices • Average Savings per year per cubicle = 132 KWh • Includes removal of 4 units during research period • Median value = 80 KWh • 80% Confidence Interval = 36.34

  10. Results – Frequency Distribution Printer 1057 kwh savings

  11. Results – # of Devices Plugged In * Number of devices plugged in is in addition to computer and monitor

  12. Measure Cost and Measure Life • Cost • $24.99 per unit, Non-Volume, Retail • Labor cost - $3.50 (10 Minutes per unit at $20/hour for installation) • Measure Life • 4 years

  13. Cost Effectiveness

  14. Measure Workbook Results

  15. Measure Workbook Results

  16. Measure Checklist

  17. Measure Requirements • Must be installed in commercial offices occupied a minimum of 50 hour per week • Must be at least 1 device plugged into strip, in addition to desktop/laptop/monitor • Okay to use with Network PC management as long as more than desktop/monitor plugged in

  18. Continued Research • Follow up with metered units periodically to check if still installed • BPA to conduct metering on additional 24 work spaces with same metering process • Study using occupancy sensor devices

  19. Motion for Approval • Motion to approve UES estimate to active status for smart power strips (load and occupancy sensing) in commercial office applications, with a sunset date of September 2013 (2 years)
